Research Interests:

Our research is generally focused on the development of fluorescence-based biosensors for analytes of clinical and environmental interest, particularly metal ions. The biological and pathological roles of metal ions such as zinc, copper, cadmium, nickel and cobalt in humans are of growing interest in a variety of diseases, including Alzheimer disease, stroke, epilepsy, cancer, macular degeneration of the eye, and others. By using biological molecules such as carbonic anhydrase re-engineered to sense the metal by displaying a change in fluorescence, we obtain biosensors of outstanding sensitivity and selectivity which permit picomolar concentrations to be quantitatively imaged inside cells, or to be determined in complex media such as sea water. These biosensors can also be expressed inside cells of many types, or even inside individual subcellular organelles such as mitochondria. In addition, the biosensor can be incorporated into a fiber optic system that permits real time determination in a living organism, or in inaccessible sites such as the depths of the ocean.
